Tissue Distribution Click here for help
Mouse embryo. Expressed from E8.5 to E11.5. At E8.0-E9.5, expression was restricted to the lateral neural folds of the neural plate. Gpr161 is expressed at all examined stages of lens development: lens pit (E10.5), lens vesicle (E11.5), primary lens fiber cells (E12.5), and differentiating secondary lens fiber cells (E14.5). At E12.5 and E14.5, Gpr161 transcripts are restricted to differentiating lens fiber cells and are absent from the proliferating anterior lens epithelium. Gpr161 is also expressed in a number of other structures from E9.5 to E12.5, including the ventricular zone of the developing CNS (E9.5-E11.5), the fore and hindlimbs (E12.5), and the retina (E10.5-E14.5).

Physiological Consequences of Altering Gene Expression Comments
GPR161 is required for right-left patterning in zebrafish development via modulation of Ca2+ in cells surrounding Kupffer's vesicles [2].

Clinically-Relevant Mutations and Pathophysiology Comments
A C-terminal truncation (deletion) mutation in Gpr61 causes congenital cataracts and neural tube defects in the vacuolated lens (vl) mouse mutant. Foxe3 is a genetic modifier that interacts with GPR161 to regulate lens development [3]. The mutated receptor is associated with cataract, spina bifidia and white belly spot phenotypes in mice [1].
Biologically Significant Variant Comments
The vacuolated lens C-terminal GPR161 truncation mutation affects receptor mediated endocytosis [3].
